Are there missable achievements in ONE BTN BOSSES?

ONE BTN BOSSES achievement guide, roadmap and tracker

ONE BTN BOSSES is a one-button boss-rush bullet-hell with a roguelite twist and a cracking soundtrack. You auto-circle each arena and press a single button to attack, dodge and time everything; between fights you draft cards to build a run. A short, stylish campaign of themed corporate bosses, plus an endless "rift" mode where the deeper unlocks live.

The campaign is five bosses in order (1. Clocked In through 5. Buzzwords) - clear them to roll credits. Everything else lives in the rifts and the unlock grind: challenge runs like Pacifist (die holding the Pacifist card), Commoner (no rare cards) and Tons of Damage (100+ dps), the completion sweeps Completionist and CompletioniSSSSSSt (every level, then every level at S rank), and the big grind The Grind (buy every ability and palette). A couple are properly hidden - Revolution, The Forbidden One. See each note below.

10 to collect

The Forbidden One

Ultra rare0.7%

ObjectiveOptional

Hidden achievement. Collect the rare card "Fragment of Aidoxe" five times in a single rift. Each fragment you hold raises the drop chance of the next, so bank a couple early from rift rewards, then farm minibosses, rests and shops (where rares are likeliest) to stack all five.
